Mucillage and Toxic algae Ostreopsis ovata

Also in this year we are witnessing the now common and usual phenomenon of the inflorescence of marine mucilage along the coasts of our sea. At the same time as the mucilage, however, an excessive proliferation of the microalgae Ostreopsis cf. Ovata. Qhese two phenomena should not be connected or at least should not occur at the same time so frequently...

Invasion of the Sea walnut Mnemiopsis leidyi

Also this summer we are witnessing the invasion of the Mnemiopsis leidyi or Sea walnut. This year we are in early July and the sea water is slowly warming up as always in summer. Punctually after a short and intense sea storm we witness an invasion of jellyfish, plastic, tree trunks and branches, various floating debris and as now every year also the Mnemiopsis leidyi, the now infamous Sea walnut. ...

Blue Crab invasion

In Italy, public awareness of the detrimental impact of this species on local molluscs is rapidly growing and, especially in the Po delta area and on the Adriatic sea coast, eradication efforts are undergoing, both by local authorities and by local fishermen. From the 2000s until 2023 the species was reported throughout Italy. We met her, Callinectes sapidus, in Rosignano Solvay in the Province of Livorno where we took the photos and video you are seeing.

Dash-and-dot goatfish in Mediterranean Sea

We met the Dash-and-dot goatfish Parupeneus barberinus in Mediterranean sea of Cyprus while snorkelling among the rocks of the island. We did not expect to have this meeting in the Mediterranean because it is a tropical fish present in all tropical seas and in particular in the Indian Ocean and the Pacific Ocean.

Unknow species

This video was taken last Saturday (14/10/2023) during an inshore dive at about 15 meters deep. I mention the precise date because during the canonical 3 minutes of decompression at a depth of 3 meters hanging from the chain of one of the "safe water" signaling buoys, about 200 meters from the rocky and jagged coast, I decide to check the temperature of the water and the computer measured 25°C. ...

Red Squirrelfish

We met the Red Squirrelfish (Sargocentron rubrum) in the sea of ​​Cyprus while snorkelling among the rocks of the island. We did not expect to have this meeting in the Mediterranean because it is a tropical fish present in all tropical seas and in particular in the Indian Ocean and the Pacific Ocean. The reason for this sighting, as indeed for other tropical species now present in the Mediterranean, we owe it to the climatic warming of the sea, which creates favorable conditions, and to the Lessepsian migration: that is, to the entry and stabilization of animal and tropical species from the Channel of Suez.

Mnemiopsis leidyi invasion

And also this summer we found ourselves faced with the now regular invasion of the Sea walnut, Mnemiopsis leidyi (warty comb jelly or sea walnut). This phenomenon is becoming more and more frequent throughout the summers, and it is now clear that the main cause of these invasions is the increase in sea temperature. ...

Blue crab - Callinectes sapidus

Even we at intotheblue.it could not miss the infamous and by now famous this summer, Blue Crab - Callinectes sapidus - also known as Blue King Crab. We filmed it after several reports, on the stretch of coast between Vada and Rosignano Solvay, luring it with a bait to film it with the camera. This alien species has colonized the Mediterranean for at least fifty years but has spread by invading the coasts in recent years perhaps precisely because of the now inevitable warming of the waters of the Mediterranean Sea. ...

Nimble spray crab - Percnon gibbesi

Percnon gibbesi is a species of crab. It is one of at least two species commonly called "Sally Lightfoot" (the other being the semi-terrestrial Grapsus grapsus from the Pacific coast of the Americas), and is also referred to as the nimble spray crab or urchin crab. It has been described as "the most invasive decapod species to enter the Mediterranean". It populates the rocky ravines of the infralittoral plain at a depth ranging from a few centimeters to a maximum of 30 meters. This video was shot in the reefs of the island of Pantelleria in the Sicily Channel.

Australian spotted jellyfish

Phyllorhiza punctata, also known as the floating bell, Australian spotted jellyfish, brown jellyfish or the white-spotted jellyfish, is a species of jellyfish belongs to the Rhizostomatidae Family and the genus Phyllorhiza. The species has been found in the waters off the Mediterranean Sea since at least 1965. While it is not known how it was introduced to these regions, it has been theorized that budding polyps may have attached themselves to ships, or were carried in a ship's ballast tank which was subsequently dumped.

Salpa maxima

Salpa maxima also arrived in the upper Tyrrhenian Sea or lower Ligurian Sea, that is, in the waters of Livorno and the province where we often dive. It is a Tunicate; at first sight it looks like a cross between a fish and a jellyfish but it is neither, it is actually a transparent invertebrate belonging to the order of the Salpidae subphylum Tunicata, coming from the deepest oceans and very rare in the Mediterranean....

The Spotted sea hare, Aplysia dactylomela, is a species of large sea slug, a marine opisthobranch gastropod in the family Aplysiidae, the sea hares. As traditionally defined, this species of sea hare was cosmopolitan, being found in almost all tropical and warm temperate seas, including the Mediterranean Sea where first seen in 2002 and likely self-established due to increasing temperatures.
